HESI A2 Vocabulary Quizlet

1. Select the meaning of the word 'vital' in the sentence: 'It is vital for the victim of a serious accident to receive medical attention immediately.'

Correct answer: C

Rationale: In this context, 'vital' means absolutely necessary or essential, indicating that receiving medical attention immediately is crucial for the victim's well-being. Choice A, 'recommended,' suggests a level of advisability rather than necessity. Choice B, 'discouraged,' is the opposite of the meaning conveyed by 'vital.' Choice D, 'sufficient,' implies having enough of something, which is not the intended meaning in the given sentence.

2. As the leader of a group, the charge nurse is open to new ideas and thoughts of the group. The charge nurse encourages the group to participate in making decisions. This type of leadership is called:

Correct answer: C

Rationale: The correct answer is 'Democratic.' A 'Democratic' leadership style involves the leader being open to new ideas and thoughts from the group and encourages group participation in decision-making. This style promotes collaboration, communication, and inclusivity in decision-making processes. 'Laissez-faire' leadership is characterized by a hands-off approach with minimal guidance or direction. 'Autocratic' leadership is where the leader makes decisions without much input from the group. 'Direct' leadership is not a widely recognized leadership style in this context.

3. Which statement would not be inferred by the reader in the passage about Barefoot Running?

Correct answer: D

Rationale: The passage does not imply that Olympic runners specifically ran barefoot before 1950. While it discusses historical context regarding running shoes, the claim about Olympic runners is not substantiated within the text, making D the correct answer. It represents an inference that cannot be drawn from the provided information.

4. Fluids can be categorized based on their shear stress-strain rate relationship. An ideal fluid exhibits:

Correct answer: A

Rationale: An ideal fluid, often referred to as an inviscid fluid, is a theoretical concept used in fluid mechanics to simplify calculations. It is characterized by having zero shear stress at any strain rate. In reality, such fluids do not exist, but they serve as a useful starting point for understanding fluid behavior in idealized situations. Choice B is incorrect because a linear relationship between shear stress and strain rate defines a Newtonian fluid, not an ideal fluid. Choice C is incorrect because a non-linear relationship between shear stress and strain rate characterizes Non-Newtonian fluids, not ideal fluids. Choice D is incorrect because the high dependence of viscosity on temperature is a characteristic seen in real fluids and does not define an ideal fluid.

5. A bicycle and a car are both traveling at a rate of 5 m/s. Which statement is true?

Correct answer: B

Rationale: Kinetic energy is determined by both the mass and the velocity of an object. While both the bicycle and the car are moving at the same velocity (5 m/s), the car has significantly more mass than the bicycle. As a result, the car has more kinetic energy than the bicycle, even though their speeds are identical. Therefore, choice B is correct. Choices A, C, and D are incorrect because they do not consider the influence of mass on kinetic energy. Choice A is incorrect as the car has more kinetic energy due to its greater mass. Choice C is incorrect because the vehicles have different masses. Choice D is incorrect as both the bicycle and the car possess kinetic energy.
